Media Player Signaling Scope for Coordinated Audio-Video Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In audio-visual separation scenarios, users need to control audio and video devices separately using Bluetooth and Wi-Fi protocols, leading to complex operations and a poor user experience due to the lack of interconnection and coordination between these protocols.
Innovation Solution
A transmission method and apparatus that uses signaling scopes to indicate whether control signaling acts on a point-to-point or device set scope, enabling coordinated control and reducing the need for complex operations by clearly defining the scope of control signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate control operations are performed for audio and video devices using different protocols, then protocol independence and device compatibility are maintained, but user operation complexity increases and user experience deteriorates
Solution Approach 1:
The patent introduces a mediator mechanism where the terminal device receives control signals and determines their scope of action through indication information. This mediator approach allows different protocols to coexist while providing unified control interface, resolving the contradiction between protocol independence and operation simplicity
Solution Approach 2:
The control signal is designed with universal applicability through scope indication mechanisms. A single control signal can act on individual devices or multiple devices within a device set, providing multi-functional control capability that simplifies user operations while maintaining protocol-specific functionality
2Measurement precision
If control signaling acts on individual devices only, then precise device control is achieved, but coordinated control across multiple devices becomes difficult
Solution Approach 1:
The control signal scope is made dynamic through indication information that can specify either individual device targeting or device set coordination. The system adapts the control signal's scope based on the indication, allowing a single signaling mechanism to provide both precise individual control and coordinated multi-device control as needed
3Reliability
If control operations are performed through multiple separate protocols, then device-specific control precision is maintained, but overall system complexity increases
Solution Approach 1:
The control system is segmented into protocol-specific control paths that maintain reliability, while a higher-level coordination mechanism manages the overall complexity. The indication information mechanism segments the control logic to handle different device sets appropriately, reducing overall system complexity while preserving device-specific control reliability
